SAN FRANCISCO—The San Francisco 49ers got an extra third-down play in the first half because of an officiating error — and scored a touchdown on it.

After a third-and-6 play at the Green Bay 10-yard line in the second quarter, Colin Kaepernick was hit out of bounds by Clay Matthews. The Green Bay linebacker drew a personal foul penalty, but so did 49ers tackle Joe Staley for unsportsmanlike conduct.

Because both penalties came after the play ended with Kaepernick stepping out of bounds without gaining a first down, it should have become fourth down. The league said the penalties were dead-ball fouls and the ball should have been spotted at the Packers 6, making it fourth-and-2.
